如何以编程方式创建可绘制的形状(Android)

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#FF0000" /> <!-- 填充颜色 -->
    <stroke android:color="#000000" android:width="2dp" /> <!-- 边框颜色和宽度 -->
    <corners android:radius="10dp" /> <!-- 圆角半径 -->
</shape>

<View
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:background="@drawable/rectangle_shape" />

ShapeDrawable shapeDrawable = new ShapeDrawable(new OvalShape());
shapeDrawable.getPaint().setColor(Color.RED); // 设置填充颜色
shapeDrawable.getPaint().setStyle(Paint.Style.STROKE); // 设置边框样式
shapeDrawable.getPaint().setStrokeWidth(2); // 设置边框宽度

View view = findViewById(R.id.my_view);
view.setBackground(shapeDrawable);
